Hydrogen Peroxide Horizontal Storage Tank

Transcription

1 Introduction Solvay Chemicals, Inc. has designed a hydrogen peroxide storage tank that is relatively easy to transport, install, and assemble. This tank is available in capacities of 7000, 10000, and gallons to meet different storage requirements. The tank is skid mounted so that no special foundation is required, but it should be located on a level surface, placed inside a dike to contain any spills, and have a safety shower and water hose nearby. All other metal parts contacting hydrogen peroxide should be passivated prior to being placed in service. Installation The tank must be lifted only when it is empty. ylon straps are preferred for lifting, however, cables can be used. Either nylon straps or cables must be sized to handle a minimum of 150% of the weight of the tank (refer to Process Engineering Diagram T-1 for weight and dimension information). If nylon straps are used, place on the outside of the saddles and inside of the bottom nozzles. If cables are used, place boards between the cables and the tank (to protect the tank) before connecting the cables to the saddles. Refer to the decal on the tank for the recommended rigging method. Assembly There are a few steps required to prepare this tank for safe hydrogen peroxide service. A fill line with brace, and a wooden crate containing the accessories are shipped with the tank. Refer to Process Engineering Diagram T-1 for nozzle locations. 1. Manway - Remove the tie-down from the manway (but leave it closed) so that it can act as an emergency relief vent in case of rapid decomposition. ever tie down the manway when the tank is in H 2 O 2 service. 2. Vent Filter - Remove the 6" blind flange from one of the nozzles on top of the tank and install the filter. 3. Remove a 2 blind flange from the top of the tank for the fill line. Position it so that it is conveniently located for deliveries. Use the accompanying brace to support the fill line. 4. Sight Glass - Remove the two ¾" blind flanges from the nozzles on the side of the tank and install the ¾" valve to the bottom nozzle. Install the sight glass, taking care to distribute the stress evenly on both flanges. Install the ¼" drain valve on the bottom of the sight glass. Close all valves. 5. Outlet Valve - Remove the 2" blind flange from the nozzle on the bottom of the tank and install the outlet valve assembly. Close the outlet valve. 6. Miscellaneous - Uncover the tank label and safety poster on the tank. Leave the other blind flanges in place to prevent contamination of the interior of the tank. Store the blind flanges that were removed in the crate for reuse when returning the crate. Page 1/6

2 Disassembly The tank must be prepared for safe transport and to comply with DOT regulations. 1. The tank must be completely emptied of hydrogen peroxide and then a minimum of 100 gallons of water (the highest quality available) added. The flanges on all bottom nozzles should be removed to drain any heel. Persons working with hydrogen peroxide should be familiar with safety and handling procedures and should always wear the appropriate personal protective equipment including goggles and gloves. 2. The tank must be disassembled (reverse the steps used in assembly) and all of the accessories packaged in plastic and replaced in the original wooden crate. 3. Cover the words "Hydrogen Peroxide" wherever they are located on the storage tank (tank label, safety posters, etc.). Recommended Maintenance 1. The vent filter should be inspected periodically for particular buildup and replaced as needed. 2. The sight glass tubing should be inspected for leaks each time it is used and repaired as needed. 3. Any damaged gaskets must be replaced. Pre-Transport Checklist The following checklist is recommended to assist in complying with the DOT regulations. It should be faxed to Solvay Chemicals at when the tank is ready for return.

4 Storage and Handling Store hydrogen peroxide in the original vented container, upright, in a cool, ventilated area where it is protected from damage, or in bulk storage tanks made from approved alloys of aluminum or stainless steel. Do not store other chemicals, fuels, or combustible materials near hydrogen peroxide. ever return unused hydrogen peroxide to the storage container. When empty, rinse all peroxide containers thoroughly with clean water before discarding. Use only approved material for pumps, piping, and hoses. Safety Persons working with hydrogen peroxide should be familiar with personal protective equipment, first aid measures and the proper safety and handling procedures. Consult the Material Safety Data Sheet (MSDS) for appropriate information. Prevent accidental decomposition by keeping the product free of contaminants. Prevent fires by avoiding accidental spills. Water is the preferred method for extinguishing fires in which hydrogen peroxide is present. Spills and leaks should be contained, diluted with copious amounts of water and disposed of in compliance with local regulations. Hydrogen peroxide storage or handling areas should be equipped with a safety shower, an eyewash station, and a water hose. First Aid In case of product splashing into the eyes and face, treat eyes first. Eye contact: Flush eyes immediately with water for at least 15 minutes. Call a physician. Skin contact: Immediately flush skin with water while removing contaminated clothing and shoes. Call a physician if irritation persists. Inhalation: Remove the victim from the contaminated area to fresh air. Call a physician in case of respiratory symptoms. Ingestion: Consult with a physician immediately in all cases. DO OT induce vomiting. If victim is conscious, rinse mouth and give fresh water. Danger: Hydrogen Peroxide solutions are strong oxidizers and corrosive to the eyes, mucous membranes and skin. Consult the MSDS for the appropriate Personal Protective Equipment to wear when handling hydrogen peroxide. In case of contact with the eyes, skin or clothing, flush with large amounts of water for 15 minutes. In case of ingestion, sit upright, drink large quantities of water to dilute the stomach contents and seek immediate medical attention. Product in contact with combustible materials may cause fires.
